You Walked around a circle which has diameter of hundred metre how far you worked

314.16 metres

Step-by-step explanation:

The answer to this problem is essentially just the circumference of the circle.

The circumference, or perimeter, is denoted by C = 2πr = πd, where r is the radius (and half the diameter) and d is the diameter.

Here, the diameter is 100 metres, so plug this in for d:

C = πd

C = π * 100 ≈ 314.16 metres

The answer is about 314.16 metres.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
